“The Galactic Senate, also referred to as the Republic Senate, Galactic Congress, Republic Congress, or Old Senate (during the time of the New Republic), was the legislative and executive branch of the Galactic Republic that was located on Coruscant. Its primary duties were to mediate any disputes between star systems, worlds and cultures, to regulate trade between systems, to protect and care for citizens in need and to provide mutual defense in face of threats to the Republic.” – Wookieepedia: The Star Wars Wiki http://starwars.wikia.com/wiki/Galactic_Senate
